I still can't figure out what would take 5 DVD's unless there is more to it than just changing out the maps themselves.
Actually, I did it last year when the phone people mistakenly were told that the update worked on the Altima. So, I installed the map discs (four of them), but the fifth one (the firmware update) could not be read. As a result, I had a non-working GPS (new maps did not work with old firmware) and, in the end, Nissan had to replace the whole unit under warranty. Navteq contacted me a couple of weeks later to tell me not to install it (duh) and refunded my money when they noted that there had been an error on their side.
I just saw the new update was available so I sent a letter to Navteq to see if they would work with me given the issues they caused last year (multiple dealershp visits, couple of months with no working GPS, etc.). I could see that the maps and POIs were greatly updated as they reflected all of the very recent construction in my area (but couldn't do anything else with it), but cannot comment on functional improvements (such as the graphics, song title database, etc. for example) as I was never able to get that disc to install. So, yes, it does install new firmware, but I cannot comment on what new/improved features that firmware has. You might want to check on another board to see what the 2012 firmware did for the Maxima for example as they use the same X9 maps.
The main annoying thing was that it required the engine to be on for the duration so you burn about 1/8 of a tank of gas installing it since it takes a couple of hours. But, the process was as simple as installing the disc in the DVD slot and swapping it out as each disc was completed.
I'm definitely looking forward to updating the maps finally and hope Navteq does the right thing so that I can.
